Definitions

  • the invention relates to a cable conveyor system of a type including a circuitous tube and a cable with a plurality of discs attached thereto for driving granular or powdery materials through such tube to a point of desired delivery.
  • the prior art shows very large contact support surfaces on the driving wheel because it is necessary to support the cable sufficiently to keep it in the shape of a loop. If there are insufficient support surfaces on the driving wheel, excessive flexing of the cable will occur, which will result in premature failure of the cable.
  • the support surfaces on the drive wheels in the prior art consist of a groove on equally spaced projections, these grooves having a length of several times the diameter of the cable it is driving. While this provides the needed support to the cable, it allows material to accumulate between the groove and the cable if the driving wheel is disposed in the material being conveyed, the problem referred to above of causing the cable to jump off of the driving wheel.
  • the invention as claimed is intended to solve these problems by providing a conveyor system of the type including a tube, an endlesss cable having discs attached thereto at equally spaced intervals and a drive unit for driving the cable and discs through the cable for causing material to be pushed through the tube and thereby conveyed to points of destination, the drive unit being of an improved design which allows the driving wheel to be disposed within the material being conveyed.
  • the driving wheel includes a circular member which is driven by a prime mover such as an electric motor through a gear box.
  • the circular member has a plurality of projections connected at one end thereof to the circular member.
  • the other end of the projections has a groove therein for receiving and supporting the cable, a driving surface on every other projection contacts one side of the discs to move the cable through the tube.
  • the width of the projection or length of the groove is no more than one and one-half times the diameter of the cable so that materials do not accumulate in the groove which would cause the cable to jump off of the driving wheels.
  • Fig. 1 shows part of a conveyor system with a drive unit 10 in accordance with the invention.
  • a housing is provided and includes a bottom 11 (Fig. 3) and sides 12.
  • a drive wheel 13 is disposed within the housing and rests close to the floor 11 and is rotably disposed by attachment of a circular portion 14 rigidly attached to a plate member 15, the sleeve 14 then being rigidly attached to a shaft 16 of a differential gear box 17.
  • the plate member 15 of the drive wheel 14 has a circular portion 18 welded to the periphery thereof by means of weldments 19.
  • Drive projections 20 extend radially outwardly from and are attached to the circular portion 18 as can best be seen in Fig. 1.
  • the drive projections 20 include a groove 21 disposed in the end thereof.
  • the width of such groove and projection member 20 has been given the dimension A as is shown in Fig. 4 and the cable diameter has been given a dimension B .
  • the housing also includes interior wall members 22,23, 24 and 25 which are stationary and are rigidly connected to the floor 11.
  • lovable walls 26 and 27 are rigidly connected together and pivotally connected to the wall 25 by means of a hinge2B.
  • a compression spring 29 is provided for biasing the movable walls 26 and 27 towards the cable member 30.
  • the compression of the spring 29 is adjustable by means of a nut 32 threadably engaged upon a bolt member 33.
  • the bolt member 33 is secured to a bracket 34 which is bolted to floor 11 of the housing by means of.a nut and bolt device 35.
  • the cable 30 is of a circuitours type such as disclosed in U.S. Patent Nos. 3905473 and 4071136, for example.
  • Such cable 30 has a plurality of nylon discs members 31 rigidly secured thereto at regular intervals along the length thereof which are preferably spaced twice.the distance between adjacent ends of the drive projections to allow the drive projections to be disposed within the material being conveyed.
  • a cable biasing and following member 36 is provided which extends through a slot 37 in the wall 10 and is thereby pivotally attached to the housing .12 and is movable between the positions shown in solid lines in Fig. 1 and the position shown in dashed lines in Fig. 1.
  • a pair of tension springs 38 are secured to the end 36a which extends outwardly from the housing walls 12. These tension springs 38 are also attached to a bracket 39 which is rigidly attached to the wall 12 of the housing. These tension springs 38 tend to bias the member 36 towards the position shown in dashed lines in Fig. 1.
  • the height of member 36 is not shown in the drawings but it is approximately the same height or perhaps slightly higher than the height of the drive projections 20, but it can be as high as the asides 12 of the housing.
  • the height of the walls 22-27 are preferably about as high as the walls 12 of the housing.
  • Plate members 40 and 41 are also attached to the member 36.
  • the member 40 is pivotally attached to the member 36 by means of a pivot 42 and the member 41 is pivotally attached to the member 40 by a hinge pivot 43.
  • Stop projections are provided on the members 36, 40 and 41 such that members 40 and 41 cannot pivot downwardly beyond the point shown in dashed lines in Fig. 1 such that they tend to push the cable 30 to the position shown in dashed lines in Fig. 1.
  • An adjustable nut mechanism 44 is provided on the end 36a of the member 36 for the purpose of contacting a shut-off button 45 when the member 36 is pivoted to the position shown in dashed lines in Fig 1.
  • the switch 46 shuts off the power to the motor 47 and thereby shuts off the entire drive unit 10.
  • the motor 47 which happens to be of an electrical type, has a pulley 48 secured to an output shaft 49. This pulley 48, when rotated by the motor 47, turns the pulley 50 and an input shaft 51 of the gear box 17 which thereby causes rotation of the shaft 16 and thereby the drive wheel 13 when the motor 47 is on.
  • the alternate drive projections 20 will contact a shoulder 52 on the disc members 31 to thereby cause the cable 30 and disc members 31 to move through the housing including members 11 and 12.
  • a circuitous tube including an inlet tube 53 and an outlet tube 54 will normally be full of a granular or powdery material which will be pulled into the housing within the walls 12 and on top of the floor 11. Since this housing is filled with such material it is very important that such material not get between the cable 30 and fill the groove 21, since if this occurs the cable will jump off of the drive wheel 13 and the entire system will malfunction. It is for that reason that the dimension A cannot be more than one and one-half times the dimensionB. In other words the extent of the contact area on the top of the drive projection 20 cannot be more than one and one-half times the diameter of the cable 30.
  • the force of the tension springs 38 are considerably more than that of the compression spring 29 so that the members 26 and 27 will tend to be maintained against the other side of the disc members 31 but will be pushed along with the cable as it has slack in it.
  • This following of the cable by the walls 26 and the members 36, 40 and 42 tend to maintain a chanhel for the material being conveyed such that it does not build up excessively within the housing.
  • the wall 26 were to be rigidly affixed in the position shown in dashed lines in Fig. 1 and not movable, then feed would build up between this wall and the cable such that the cable might not be able to move to the position shown in dashed lines in Fig.
  • FIG. 5 - 8 an alternative form of the drive wheel is disclosed.
  • the embodiment of Figs. 5 - 8 is very similar to the type of drive wheel shown in U.S. Patent No. 3905473 except that drive projections 61 have a bore 62 disposed therein and a slot 63 has been cut out from the top of the projection 61 down to the bore 62.
  • the purpose of such modification of a prior art drive wheel is for the purpose outlined aboVe; that ' is specifically to make the width A of the groove 64 of the supporting projection 61a and 61b of a width of no more than one and one-half times the diameter B'of cable 30.
  • the clearance hole 62 along with the slot 63 not only insures and forms a relatively thin width for the grooves 64 but this also provides that material can be forced out of the groove 64 to one side or the other, for example into the clearance hole 62, so that it will not build up between the cable 30 and the supporting surfaces 64.
  • the particular embodiment of Fig.5 is constructed of cast aluminum but, of course, other materials of construction could be used.
  • a drive wheel 70 which has an outer rim portion 71.
  • a plurality of drive projections 72 are connected to the outer periphery of the rim 71 such as by welding.
  • These drive projections 72 are preferably of sheet metal and have supporting grooves 74 which are of a width A which is no greater than one and one-half times the diameter of cable 30, the dimension B.
  • driving projections are provided to actually push on the sides of the disc members 31 to pull the cable through the tubes 53 and 54 instead of in the manner shown in the Fig..4 embodiment wherein the heading surface of the drive projection 20 contacts a small shoulder 52 to drive the cable.
  • Upstanding portions 72a and 72b of the drive projections 72 have a space 73 therebetween to allow material being conveyed which might be between the cable 30 and the supporting surface 74 to freely be removed from such position, it being understood that a great deal of pressure is being exerted by the cable 30 onto the surface 74.
  • the drive projection flanges 75 contact the disc member 31 at the points 31a in a similar manner that the drive projections 65 in the embodiment of Figs. 5-8 contact the disc members 31 at the points 31a. It will also be very clear that the cable may be driven in either direction using any one of the three preferred embodiments disclosed herein.
